this is a professional Li-ion BMS made for us from the highest quality components by one of the leading designers and manufacturers of this type of product, not a factory second or other cheaply made item sometimes advertised on some shopping sites, Function: Detect and protect the battery from over-charge ,over-discharge, over-current short-circuit ,temperature detecting protection and automatic voltage balance function . Build with high end electronic components (High End IC and MOSFET ) ,simple structure design will let it have more stable quality working performance , Flexible application ( it can be used for less series battery by leaving some connection pins at empty status ),full set of protection measures let it works well without any influence from external unexpected accidents.
